Takashi Kumagai et al.
Nature chemistry, 6(1), 41-46 (2013-12-19)
Although the local environment of a molecule can play an important role in its chemistry, rarely has it been examined experimentally at the level of individual molecules. Here we report the precise control of intramolecular hydrogen-transfer (tautomerization) reactions in single
Hou Wang et al.
Advances in colloid and interface science, 195-196, 19-40 (2013-05-07)
Graphene, as an ideal two-dimensional material and single-atom layer of graphite, has attracted exploding interests in multidisciplinary research because of its unique structure and exceptional physicochemical properties. Especially, graphene-based materials offer a wide range of potentialities for environmental remediation and
Shafeer Kalathil et al.
Biotechnology advances, 31(6), 915-924 (2013-05-18)
Microorganisms naturally form biofilms on solid surfaces for their mutual benefits including protection from environmental stresses caused by contaminants, nutritional depletion or imbalances. The biofilms are normally dangerous to human health due to their inherited robustness. On the other hand
Guancai Xie et al.
Advanced materials (Deerfield Beach, Fla.), 25(28), 3820-3839 (2013-07-03)
Hydrogen production from solar water splitting has been considered as an ultimate solution to the energy and environmental issues. Over the past few years, graphene has made great contribution to improving the light-driven hydrogen generation performance. This article provides a
Judith P Klinman et al.
Annual review of biochemistry, 82, 471-496 (2013-06-12)
The relationship between protein dynamics and function is a subject of considerable contemporary interest. Although protein motions are frequently observed during ligand binding and release steps, the contribution of protein motions to the catalysis of bond making/breaking processes is more
